Most of you probably already do this, but about twice a year, I give my radiators a good cleaning and a little repair to ensure good air flow. I think this is important for performance and endurance. No big trick, just use plenty of warm water and a soft brush. My little trick is to staighten the fins with one of those plastic tooth picks, the one's with the floss works great. They are soft and won't harm the radiator as long as your not too aggressive. Good luck! I hope this helps.
Highway life with a street legal 2012 rmz 450. A clear answer to one of the most ask questions. How does a dirt bike handle on the street.By Roc road
2018 purchased with 40-53 hours on the stock motor, pistons, vavles, shims, transmission, everything; besides an aftermarket yoshimura slip on exhaust.
Checked the vavle clearance before I road it and they were all in spec with suzuki's service manual. Let's move on.
The bike was primary used for I dont know what. The last owner said he did some riding in the Oregon sand dunes. No idea if it was raced before that.
My goal was to turn it into a road legal dual sport. I opted for a 2012 RMZ because they come with a dignostic port behind the front number plate mounted on the ECU that when kicked over provides a constant voltage of 13.50V to 14.50V ish. To power all the road legal stuff.
Upon completion I replaced the hour meter with a Trail Tech Endurance 2 at 0 miles and 0 hours. Other then a stainless steel oil filter, changed spark plug, and cleaned air filter the engine remained stock.
I commuted with the bike to work daily which is 3 miles there and 3 back on 40 mph roads. During lunch i ride for one hour about 15-20 miles on some wood trails. Blah blah blah.
Fast forward some more and the bike has 90 accumalated hours total. I have not check the vavle clearance since getting the bike.
Most of the riding was around 45-55 mph average for top speed to 35 everywhere else.
My oil changes have been every 10 hours give or take how hard and how many miles I've driven. Changed with full synthetic maxima pro plus 10w40 oil.
Air filter was cleaned once in between, from the time I got the bike till 90 hours........ lay it on me but wait till you finish this read.
Okay so up to this time I'll reiterate that the engine is still stock. No top end rebuilts, no vavle shims, NOTHING! All OEM.
At 90 hours I changed the gearing from the stock 13/49 to 15/49 since then I've added 15 hours on it with the same riding habits as before with my longest highway/freeway trip being 30 minutes at 18 miles mostly highway miles driven at or around 65Mph. Yeah she was screaming at that too, with a 5 speed gear box. It was sketchy even with that changed gearing.
Blah blah again.
Now I'm at 110 hours and 1500 miles on a still stock motor besides transmission gearing. My vavle spacing hasn't changed. And I decided to tear down the top end to see what I'm working with. Cylinder, piston, rings, conrod, vavles, spark plug, head, etc look okay with normal wear and tear.
So in conclusion. I will order a forged piston to deal better with the higher rpms that I run at. BUT THAT AS FAR AS ENGINE MODS WILL BE IT. I haven't notice any power losses and love that gearing. It still works well down low.
Now take it or leave it but this is an honest tracker from my level of riding and mechanicle knowledge. I'm not getting paid for this or influenced by a company or brand. I'm just posting this because there is, in my opinion no real knowledge posted about this topic but a lot of people are curious.
I have a 1969 (approximately) Honda Z50. It was given to me after my uncle died. He would ride it around the dirt lake road between our families houses with a beer in one hand and a cigarette hanging out of the side of his mouth laughing the entire way. If you've ever seen or owned a Z50, they are a little ridiculous. All I wanted when I was younger was to ride his mini bike but I never got the opportunity. After he died, it sat in his garage for a number of years until i eventually came to own it.
Unfortunately after sitting for so long, it is not starting at the moment. In addition he was not much of a mechanic so it needs some serious TLC. I thought it would be a great honor to restore it in his name and put it back on those lake roads.
I need help guys. I can figure my way out around a bike but I am a little curious where to start with this old hunk. I would be happy to get it running again but I am also looking at possibly engine swapping this little guy (80cc or 125cc) if possible. And I know what you're thinking, "waste of time.. or this idiot has too much time on your hands"......agreed but I think you can agree that would be pretty badass. And for the short amount of time this thing gets used it would be a fun little project for nights at the lake.
If you have any advice on where exactly to start or if the engine swap is possible please let me know. Not looking to hear from any of you automatic 'nay-sayers,' have a little imagination and appeal to your younger 12 year old self.
So I recently purchased a 2001 YZ250 with no Engine. I am looking to make it in to a single track enduro bike. I am right now looking for some what of a complete engine and have come across one recently pulled motor out of a 2011 yz250. To my knowledge the only thing different about the motors from pretty much 99-Present is the swing arm pivot. I guess they changed sizes in 02. I was wondering if anyone knew if it is possible to interchange that 2011 engine into an 2001 frame?
